SPECIFICATION fanning part of Letters Patent No. 707,511, dated August 19, 1902.

Application filed June 18, 1901. Serial No. 65,046. (No model.)

To all whom, it may concern.-

Be it known that I, BENJAMIN F. HOARD, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a certain new and useful lVIanifolding Iablet, of which the following is a specification.

My invention relates to manifold pads or appliances by means of which multiple impressions of documents, as bills, news items, shipping-receipts, &c., may be obtained by a single operation; and it has for its object the provision of an appliance of the kind set forth simple in construction, inexpensive to manufacture, and which is efficient in practical use.

To attain the desired end, this my invention consists in the construction, arrangement, and operation of parts herein set forth.

In order to enable my invention to be fully understood, I will proceed to explain the same by reference to the drawings which accompany and form a part of this specification, in which- Figure 1 is a perspective view of a manifold-Writer made according to my invention. Fig. 2 is an edge view, and Fig. 3 a side elevation, of the same; and Fig. 4 is a view in detail of my clamp-locking device.

Like letters of reference indicate like parts in all the views.

I have found it desirable to provide a device by which copies or facsimiles may be made by interleaving sheets of plain or writing paper with carbonized paper, by means of which the matter written upon the uppermost sheet may be duplicated and in the use of which the carbon-paper may be protected and preserved without danger of wrinkling or tearing the same and the work to be done facilitated, and I have therefore constructed according to my invention an organization of the class described embodying the preferred construction of parts and their mutual relationship, combination, arrangement, and organization in a composite structure, as hereinafter described.

Referring particularly to the drawings, A denotes my base or foundation plate provided with orifices a. A clamping-piece, 0rdinarily U shape in cross-section, is secured to the base A in a movable or rocking relation by means of pins or rivets O C, passing loosely through the apertures a. The clamp B is ordinarily parallel with the base A, whereby either the upper edge I) of the clamp may contact the front face of the base-plate A or the lower edge I) of the clamp B may beheld close to the rear face of the base A at will. The sheets of paper D to be written upon, preferably interleaved with carbonized paper E, may be laid upon the front face of the plate A and slipped under the clamp B, the upper edge B of the same being raised up by means of a suitable lifting device, as the lug B. I provide means to press the edge I) of the clamp against the paper D E, and thus lock the same securely in my pad between the clamp B and the base A, as, in the present instance, by the following mechanism: The loweredge b of my clamp B is provided with an enlarged portion or offset B in which works my locking-piece F, the same being pivoted to the pin or rivet C. My locking-piece F is ordinarily wedge-shaped, the outer portion f, provided at its free end with a pin f, being thickened and the inner part f of the same being provided with'a thin edge. When the paper is placed on the base-plate, the lockingbar F is parallel with the edge of my pad, as shown in Fig. 4, and as then the said locking-piece F works in the enlarged portion or offset 13 of the clamp B the upper edge of the clamp may be lifted up and the paper slipped beneath the same. In order to lock the parts together, the locking-piece F is now pushed along the rear face of the base-plate A until the thickened edge fof the same ongages the lower edge I) of the clamp 13, and thereby forces the same away from the plate or base A, as shown in Fig. 2. The parts will now be rigidly locked together, and in order to release the paper the locking-bar F is pushed by the pin f a sufficient distance for it to move entirely out of the narrower part of the clamp B until it works again in the wider portion or offset B whereupon the clamp B maybe turned so that the lower edge I) is contacted with the base A'again and the upper edge I) raised from the said base a sufficient distance to readily allow the paper sheets to be detached. I

It will be seen that by my device the carbonized and plain paper may be readily engaged with and detached from the base without any danger of tearing or wrinkling the carbon-sheets, as the edge of my clamp moves toward and away from the paper and grasps the same practically along the entire edge thereof. There is likewise no danger of the carbonized sheets smutting off on the fingers or on the plain paper, as the locking-piece F does not come in contact with any of the sheets, but works on the opposite or rear or under face of the base A.

Manifestly the lower edge of the clampingpiece may be held against the rear face of the base by a spring; but I prefer to use a positive manually-actuated locking device, as the bar F.

As it is manifest that many changes in the construction, form, proportion, and relative arrangement of parts might be resorted to without departing from the spirit and scope of my invention, I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such changes and equivalents may be substituted therefor, and that What I claim as my invention is 1. In a manifolding-tablet, a base-plate to hold the sheets, in combination with a clampin g device secured thereto, means to hold said clamping device in a rocking relation so as to move away from the front face of the base to insert the sheets thereunder, and with means to lock the clamp, sheets and baseplate immovably together along or near the edge of said base.

2. In a manifolding-tablet, a base-plate to hold the sheets, in combination with a clamping device secured thereto, means to hold said clamping device in a rocking relation, so as to move away from the front face of the base to insert the sheets thereunder, and with means pivoted to the base-plate to lock the clamp, sheets and base-plate immovably together along or near the edge of said base.

3. In a manifolding-tablet, a base-plate to hold the sheets, in combination with a clamping device secured thereto, means to hold said clamping device in a rocking relation, so as to move away from the front face of the base to insert the sheets thereunder, and with means whereby the said clamp may grasp the sheets along or near the edge of said base consisting of a locking-piece to engage the clamp on the rear face of the base.

4. In a manifolding-tablet, a base-plate to hold the sheets, in combination with a rocking U-shaped clamping device secured thereto, means to hold the clamp in a rocking relation so as to move from the front face of the base to insert the sheets thereunder, and with means to engage the clamp and front face of said plate along or near the edge of said base, consisting of a locking-bar to engage the clamping device on the rear face of the base.

5. In a manifolding-tablet, a base-plate to hold the sheets, provided with orifices, in combination with a rocking U-shaped clamping device secured thereto and provided with holding pins or rivets to work loosely in said orifices, and with means to engage the said clamp along or near the edge of the base, consisting of a locking-bar to engage the clamping device on the rear face of the base.

6. In a manifolding-tablet, a base-plate to hold the sheets, in combination With a U- shaped clamping device inclosing the edge thereof, means to hold said clamping device in a rocking relation so as to move away from the front face of the base to insert the sheets thereunder, and with manuallyactuated means to coact with the clamping device so as to hold the same together with the sheets tightly against the said plate or to allow it to rock thereon at will.

7. In a manifolding-tablet, a base-plate to hold the sheets, in combination with a cla1nping device secured thereto, means to hold said clamping device in a rocking relation so as to move away from the front face of the base to insert the sheets thereunder at one edge of said plate,and with manually-actuated means to operate the clamping device so as to hold the same together with the sheets tightly against the said plate or to allow it to rock thereon. at will, consisting of a pivoted locking-piece constructed and arranged to clamp the parts when it is parallel with the clamping device and to release the same when it is at an angle thereto.

In testimony of the foregoing specification I do hereby sign the same, in the city of New York, county and State of New York, this 3d day of June, A. D. 1901.

BENJAMIN F. HOARD.
